“…The advantage is that all nodes share the only control channel so only one control channel is required, but nodes take time to synchronize with each other. Wang et al (2008) proposed a multiple transceivers approach with which each node has several transceivers. Each transceiver is allocated an individual channel, so a node can transmit packets through different channels simultaneously.…”

“…But, the corresponding scheduling algorithm is hard to design since nodes switch channels frequently, particularly when traffic is busy. Wang et al (2008) introduced several multi-channel MAC protocols, and reserved a dedicated control channel to perform time synchronization among nodes. The disadvantage is that it requires a dedicated control channel, which decreases network efficiency since the control channel is often a communication bottleneck.…”

“…More and more wireless devices, such as notebooks, smart phones, and sensor networks, support wireless protocols, and the convenience and rather low cost of wireless-device deployment have made wireless networks more attractive than before. But in wireless networks, some problems, e.g., the hidden node problem (Leu and Huang, 2008), radio collision (Le et al, 2007), and multi-channel hidden terminal problem (Wang et al, 2008), need to be solved before we can efficiently enjoy wireless network convenience. Baiocchi et al (2004) compared wireless network transmission throughputs for a single channel and multiple channels given a hidden-node scenario and a non-hidden-node scenario.…”

“…Use of multiple channels in a wireless sensor network increases throughput with provision of higher bandwidth and reduces delay by parallel transmissions of nodes in same neighborhood [14]. Sensor nodes usually have single radio transceiver therefore cannot work on multiple channels simultaneously.…”

Use of multiple frequency channels in a wireless sensor network alleviates bandwidth limitations in communication. Moreover, operating wireless sensor network with low duty-cycle conserves energy and thus prolongs network lifetime. With the benefits, these approaches bring challenges for data dissemination. In data dissemination each node tries to forward data to maximum neighbors in order to achieve maximum network coverage. It becomes difficult for each node to make forwarding decisions in a context where multiple channels are available with different channel conditions and many of its neighbors are sleeping due to low duty-cycle. Hence, selection of the right channel is a critical issue for each node to disseminate data reliably and efficiently.In this paper, we present a distributed channel selection scheme for efficient data dissemination in low duty-cycle multichannel multi-hop wireless sensor network and name it as a Smart Channel Selection Scheme. Through simulations, we have analyzed the performance of our proposed approach and compared it with three relevant approaches i.e. Random Channel Selection, Channels' Condition based Channel Selection, and Neighbors based Channel Selection. Simulation results confirm that our approach outperforms the relevant approaches in terms of reliable and efficient data dissemination. With proposed Smart Channel Selection Scheme we can achieve more than 70% packet delivery ratio under as low as 40% duty-cycle.

Pervasive systems, which are described as networked embedded systems integrated with everyday environments, are considered to have the potential to change our daily lives by creating smart surroundings and by their ubiquity, just as the Internet. In the last decade, "Wireless Sensor Networks" have appeared as one of the real-world examples of pervasive systems by combining automated sensing, embedded computing and wireless networking into tiny embedded devices.A wireless sensor network typically comprises a large number of spatially distributed, tiny, battery-operated, embedded sensor devices that are networked to cooperatively collect, process, and deliver data about a phenomenon that is of interest to the users. Traditionally, wireless sensor networks have been used for monitoring applications based on low-rate data collection with low periods of operation. Current wireless sensor networks are considered to support more complex operations ranging from target tracking to health care which require efficient and timely collection of large amounts of data. Considering the low-bandwidth, low-power operation of the radios on the sensor devices, interference and contention over the wireless medium and the energy-efficiency requirements due to the battery-operated devices, fulfilling the mentioned data-collection requirements in complex applications becomes a challenging task.This thesis focuses on the efficient delivery of large amounts of data in bandwidth-limited wireless sensor networks by making use of the multi-channel capability of the sensor radios and by using optimal routing topologies. We start with experimenting the operation of the sensor radios to characterize the behavior of multi-channel communication. We propose a set of algorithms to increase the throughput and timely delivery of the data and analyze the bounds on the data collection capacity of the wireless sensor networks. The main contributions of the thesis are listed as follows:• Contribution 1 -Characteristics, challenges and the use of multi-channel communication in wireless ad hoc networks and wireless sensor networks: We review the state of the art channel assignment protocols in wireless multi-hop networks, particularly in wireless ad hoc networks and wireless sensor networks. We classify the existing solutions according to the number of transceivers required per node and according to the dynamics of the channel assignment. Since the channel assignment methods designed for general wireless ad hoc networks may not be directly applicable to wireless sensor networks, we give brief comparisons of them and discuss the additional challenges and requirements for wireless sensor networks.• Contribution 2 -Characterization of multi-channel interference: The assumption of perfectly orthogonal, interference-free channels, which is adopted in most of the multi-channel communication studies, may fail in practice. Radio signals are not limited to their allocated frequency band, but cause interference in adjacent bands as well -how much depends on...
